Situs inversus, a left-to-right transposition of the normally asymmetrical organs of the body, is a rare anomaly that occurs in 1:5,000-1:10,000 adults. In the total form, the thoracic organs, as well as the abdominal organs, are completely reversed in a "mirror image" of their normal arrangement. Herein, we present a case of an adenocarcinoma of the proximal bile duct in a 68-year-old man with total situs inversus. Without any technical problems, he successfully underwent a bile-duct resection and bilioenteric anastomosis. He did well postoperatively, and after one course of chemotherapy, was discharged on postoperative day 12. A review of the international literature on this subject is presented.

PURPOSE: To investigate the immunologic effect of the gasless laparoscopic procedure, we compared it with an immunologically effective, gas insuffulated (pneumoperitoneal) laparoscopic procedure. METHODS: The temporal immune responses in two similar groups of patients randomized to gas vs gasless laparo scopic cholecystectomy were analyzed. The patients were matched by age, weight, and operation time. Immune parameters, including serum white blood cell count and TNF-alpha, INF-gamma, IL-6, IL-8, cortisol and ESR levels, were assessed preoperatively and on postoperative days 1 and 3 between the two groups. Also during the operations, cytokines were checked in cultured peritoneal macrophages. RESULTS: The results were as follows: 1) Serum cortisol and ESR levels were not statistically different between the two groups. White blood cell counts were also not statistically different. 2) The preoperative and postoperative day 1 and days 3 serum TNF-alpha, INF-gamma, IL-6, and IL-8 levels in the two group were not statistically different. However, an immediate decrease cytokine levels was significant in both groups after postoperative day 1. 3) Especially cytokine levels were more increased in cultured peritoneal macro phages than in serum, but difference between the two groups was not statistically significant. CONCLUSION: From our results the beneficial effects of immunology in a gasless laparoscopic procedure were not different from those in a gas laparoscopic procedure. Rather, immediate preservation of the immune function during the postoperative period was detected in both groups.

PURPOSE: Anal diseases are a common complication among patients with leukemia, and the perianal abscess may prove to be the most fatal among anal diseases. We report here the prevalence, the treatment methods, and the prognosis for anal diseases among patients with leukemia. METHODS: Among the 310 patients who were diagnosed with and treated for leukemia between October 1999 and September 2000, we investigated the medical records of 53 patients with complications due to anal diseases. RESULTS: Among the 310 patients with leukemia, 53 (17.1%) reported anal diseases. There were 30 patients with hemorrhoids, 15 patients with a perianal abscess, 3 patients with an anal fistula, 3 patients with a fissure and 2 patients with hemorrhoids and fistulas. Anal pain was the most common complaint. Conservative treatment improved the symptoms in 42 patients (79.2%) while surgery was necessary in the remaining 11 patients (20.8%). A hemorrhoidectomy was undertaken in 4 patients, a drainage procedure in 4 paients, and a fistulotomy in 3 patients. Throughout the study period, 6 patients died (11.3%), 3 of them with perianal abscesses. Among the 15 patients with a perianal abscess, 13 showed fever (87%), and 9 patients underwent drainage (4 surgical drainages and 5 natural drainages). E. coli was the most commonly cultured organism. CONCLUSIONS: The incidence of anal diseases in patients with leukemia was high. Nonsurgical methods were sufficient for hemorrhoids and fistulas. For a perianal abscess, drainage should be undertaken when abscess formation is evident. When abscess formation is not evident, medical treatment is the primary modality, and surgery should be considered only when medical treatment fails to improve or worsens the patient's condition, but the prognosis is poor.

PURPOSE: Laparoscopic management of intestinal obstruction is hypothetically attractive, However little is known about this procedure in our country. With new advances in diagnostic and therapeutic tools such as laparoscopic procedures, the management of intestinal obstruction has become feasible. METHODS: In order to analyze the clinical results of laparoscopic adhesiolysis, a retrospective review of a consecutive series of 20 cases of intestinal obstruction unresponsive to medical management was done between 1997 and 2000. RESULTS: The mean surgical time for the laparoscopic procedure was 75 min and two cases were converted to open surgery due to dense adhesion and intestinal strangulation. The characterization of adhesion type included 10 cases with simple fibrotic band, 4 cases with multiple fibrotic band and 5 cases with dense adhesion. Additionally, the most common site for adhesion was the small intestine and colon (12 cases). The mean diet start time was 2.3 days, mean hospital stay was 4.7 days and totally mean analgesic use was 1.6 times. CONCLUSION: Laparoscopic management of adhesive bowel obstruction is feasible and safe in experienced hands. The laparoscopic procedure also is an excellent diagnostic modality in case of obstruction, and the majority of these cases can be simultaneously managed laparoscopically. A laparoscopic approach is recommend as a first choice of treatment for selective cases of intestinal adhesion.

Presentation of antigen in a suitable form to lymphocytes is prerequsite for the initiation of primary immune response. Dendritic cells (DC) provide an effective pathway for presenting antigens to lymphocytes in situ. The aim of this study was to establish a dendritic cell-line from human tonsils and to investigate the changes in surface phenotype during culture. Immunohistochemical studies using various surface markers indicated that cultured DC were follicular dendritic cells (FDC) from human tonsils. Cultured DC showed typical dendritic morphology at early stage of culture. Their shape changed into fibroblast-like cells over culture time. Surface phenotype study suggested that cultured DC were distinct from human fibroblast. Antigenic pattern of FDC was changed during culture; I-ILA-DR antigens decreased and HJ2 antigens increased with aging of culture. Functional characteristics of human tosillar FDC will be investigated in the future.

OBJECTIVE: The aim of our study was to make a practical comparative evaluation of the first and second trimesters in order to determine the period during which a higher yield of fetal nucleated red blood cells (FNRBCs) can be obtained. METHODS: NRBCs were isolated from maternal blood during the first and second trimesters of pregnancy using double Percoll gradients with different osmolarities. Magnetic activated cell sorting was performed with Kleihauer-Betke stain. We isolated fetal NRBCs from 10 mL of samples of maternal blood and determined fetal sex and fetal aneuploidy by fluorescence in situ hybridization (FISH). RESULTS: The average number of NRBCs was 9.85 in samples obtained during the first trimester and 14.88 in samples obtained during the second trimester (P=0.07). The average number of NRBCs with Y chromosome signals was 5.73 in the first trimester and 8.22 in second trimester (P=0.56). However, the percentage of NRBCs with Y chromosome signals in the first trimester (70.6%) was significantly higher than in the second trimester (59.8%) (P=0.049). We diagnosed the blood samples from 7 pregnant women having fetal aneuploidy using this method and the number of NRBCs was 18.4. CONCLUSION: The method using Percoll osmolarity and a double density gradient system may be a very useful method for separation of NRBCs in the first trimester of pregnancy and also in the second trimester.

The korean society of otolaryngology has had and experience on intraining examination since 1992. We also had the fortieth annual board examination for specialist in 1997. But we have no evidence on the validity of these tests yet. The aim of this study is to examine the validity of the intraining examinations as a tool of formative evaluation, to present a personal progress index demonstrating constructive validity, and to examine the validity of the board examination as a tool of summative evaluation. We did statistic analysis on the consecutive personal scores of 1995 and 1996 intraining examinations, and 1997 written and oral board examinations. Analysis of the averages, standard deviations, distribution curves, and Wilcoxon singed rank test on the scores of 1995 and 1996 intraining examinations demonstrated the constructive validity. Chi-square test revealed that those who had low scores in intraining examinations of two consecutive years had low scores in 1997 board examinations and personal progress index demonstrated the predictive validity. Correlation and linear regression analysis demonstrated a strong correlation between 1997 written and oral board examination. Analysis of the averages, standard deviations, distribution curves, and Spearman rank correlation coefficient revealed that 1997 written board examination had higher concurrent validity than the that of oral examination.

Lymph node metastasis is found in 10-15% of patients with early gastric cancer; however, metastatic nodes forming giant abdominal masses or distant metastases are extremely rare. A 51-year-old male, HBs Ag-positive patient presented with an incidentally found huge upper abdominal mass. Imaging studies showed a 7 cm-sized epigastric mass consistent with hepatocellular carcinoma. His serum -fetoprotein level was also significantly elevated (330.6 ng/ml). Endoscopic studies revealed a suspicious early gastric carcinoma located on the lesser curvature and the anterior wall of the antrum. He was operated on with a preoperative diagnosis of hepatocellular carcinoma coexisting with an early gastric carcinoma. However, the actual abdominal tumor was a metastatic lymph node resulting from a gastric carcinoma which was located around the hepatic artery. Accordingly, he underwent a subtotal gastrectomy with the D2 lymph node dissection and the removal of the metastatic node. Postoperatively, he did well without any complications. His serum -fetoprotein level decreased to 49.3 ng/ml one week after the surgery and was completely normalized 3 months later. To date, one year and 4 months after the operation, he is in good conditions without evidence of recurrence on endoscopic and imaging studies.
